Concentration of radionuclides in uranium tailings and its uptake by plants at Jaduguda, Jharkhand, India
Mining and processing of uranium ore was started in several parts of eastern Singhbhum, viz. Jaduguda, Bhatin and Narwapahar (Jharkhand) in 1968. Radioactivity in the mine tailings has to be consolidated so that it does not emanate in the atmosphere or enter the food chain. Hence, the area has been covered with 30 cm thick soil cover followed by development of plant species that do not have any socioeconomic relevance in the area. Seven native plant species of forestry origin, viz. Colebrookea oppositifolia, Dodonaea
viscosa, Furcraea foetida, Imperata cylindrica, Jatropha gossypifolia, Pogostemon benghalense and Saccharum spontaneum have been selected for experimental trials.
